Monte Carlo Simulation - A Design Tool for Fine Grain Investment Casting

拟议的SBIR第一阶段项目将开发一种软件设计工具，用于先进材料加工，以预测材料的晶粒结构。这是一个非常重要的工具，具有广泛的商业和技术价值。晶粒结构是材料性能的主要因素，在几乎所有材料加工应用中必须仔细考虑。随着工程工作站等先进计算能力的普及，计算机仿真技术在工程设计中的应用成为可能。通过计算机模拟进行材料设计已经成为可能。拟议的研究将使用细晶粒，高温合金，熔模铸造的耦合热流和蒙特卡罗模拟，以证明这种方法的可行性，材料加工设计。该模拟程序将开发的工作以前由美国国家科学基金会支持，并在文献中报道。该研究的商业化将寻求应用于晶粒结构至关重要的各种材料工艺。该项目的成功完成将使美国工业在先进材料加工领域更具生产力和竞争力。先进材料加工业的代表Howmet公司正在参与这一项目。

The proposed SBIR Phase I project will develop a software design tool that will be used in advanced materials processing to predict the grain structure of materials. This is a very important tool with wide commercial and technical value. Grain structure is a primary factor in materials properties and must be carefully considered in almost all materials processing applications. The advent of easy access to advanced computing power such as engineering workstations has made it possible to use computer simulation in engineering design. The design of materials through computer simulation is now at hand. The proposed research will use a coupled heat flow and Monte Carlo simulation of fine grain, superalloy, investment casting to demonstrate the feasibility of such an approach to materials processing design. The simulation program will be developed from work previously supported by the NSF and reported in the literature. Commercialization of the research will seek application to a wide range of materials processes where grain structure is of critical importance. The successful completion of this project will make US industry more productive and competitive in the area of advanced materials processing. A representative of the advanced materials processing industry, Howmet Corporation, is participating in this project.
